The Lowdown
Alright folks, Rusty here. Let's get straight into it. Gotta be honest, this 16-day window for Kennebunk Beach is a tough one to call. The forecast is pretty much a flat spell with no real opportunities to get a wave. We're looking at a long stretch of nothing worthwhile, with the first few days offering nothing. The water is sitting around 67°F, which is a touch warmer than normal for this time of year, a little silver lining I guess.
We start off on Friday, August 28th, with a tiny 2ft swell from the SE, but it’s all wrong. The wind is onshore and the surf quality is just poor. The energy is weak, only registering 75, and it doesn't get any better. Saturday the 29th sees a slight improvement with an offshore wind in the morning, but the swell is still a pathetic 2ft with a short period of 7 seconds. The energy is even lower at 55. That's not enough to push a paper boat. This pattern of small, weak, and onshore wind continues right through the end of the month.
We hit September, and the first few days are still a bust. The 2nd of September sees a bit of a pulse with a 2ft swell and a longer period of 11 seconds, but the wind is cross-onshore. The combined energy climbs to 126, which is moderate, but it’s still not enough to make it worthwhile with the poor conditions. The 3rd of September brings a 3ft swell from the SSE, but the period is a short 6 seconds, so it’s going to be junky and weak. The energy is 145, but again, the wind is not our friend.
The rest of the first week and into the second week is a complete write-off. We're looking at swells under 2ft with energy levels that are barely a whisper. The 12th of September has a 3ft swell from the S, but with a period of just 5 seconds, it’s going to be a close-out mess. The wind is light and cross-off, so it might look clean, but there’s just no power behind it. The energy is 76, which is nothing.
Look, the honest truth is there is no standout session here. The only thing that might be worth a mention is the brief pulse of longer period energy on the 2nd of September, but the wind kills it. This is a blank run, and for a sheltered spot like Kennebunk Beach, it's not that unusual when the swell and wind don't align. Keep your hopes up, forecasts can change, but for now, I’d hang the board up for a bit.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
